Importing a blog

I am trying to import my blog from Oxite. I noticed it does NOT support exporting to BlogML (at least the version I'm using). I am considering importing my old content directly into the database. What's the best approach to import my posts from the existing
database into Orchard database? Any suggestions?

We only had BlogML for import only. Why would anyone want to leave Oxite? It’s not like we would ever stop working on it...oh, wait.

There’s no complete tooling for clean transfer of data but you could export your data from Oxite into Orchard’s import format (as Bertrand mentioned) or try doing something with the RSS output of Oxite and the
“blog import …” command in the blog module which has some basic RSS importing functionality (thank Sébastien for that one). The command could be built upon (i.e. copied into a new module and tweaked) to add support for importing more data, like comments, if
that’s the way you (or anyone) want’s to go for importing data from some syndicated source.

Thanks everyone for their answers. I actually took the time and wrote a command line tool that connected to Oxite database and exported the data in BlogML format. Think I'll release the source in GitHub for everyone that is stuck like me. I think this was
the easiest path, as I already know BlogML format and had no idea on how Orchard's import/export works.
